- Added `minDimension` option to ensure images meet minimum size requirements for vision backends.
- Implemented logic to scale up undersized input images while respecting maximum constraints.
- Clamped minimum dimension floor to avoid resolution conflicts with defined maximum bounds.
- Replaced Bun.sleep and wall-clock timing with fake timers (vi.useFakeTimers), release gates, and deterministic polling across 15+ test files to eliminate flakiness and improve speed.
- Consolidated per-test fixture setup into beforeAll/afterAll lifecycle hooks across 20+ test files, reducing redundant initialization and improving test performance by reusing shared immutable fixtures.
- Stubbed network calls in ModelRegistry and test discovery to prevent unintended outbound requests during test execution.
- Replaced subprocess-based test coordination (file markers, Bun.sleep polling) with in-memory fakes (FakeWebSocket, FakeLspServer, VirtualClock) for deterministic, fast test execution.
- Replaced baked module-load value with per-call `isWebPExcluded()` so runtime env changes take effect.
- Only `"1"` and `"true"` (case-insensitive) enable exclusion; empty string and `"0"` are treated as disabled.
- Fast path now bypassed for WebP sources when exclusion is active.
- Explicit error surfaced when decode fails and WebP exclusion cannot be honored.
Gated WebP encoding behind OMP_NO_WEBP environment variable so that local
llama.cpp vision models (which use the STB library that lacks WebP
decoding support) can accept browser snapshots without returning HTTP 400.
Upstream reference: cline/cline PR #9837
(https://github.com/cline/cline/pull/9837) implements a similar workaround
for the same llama.cpp STB WebP incompatibility.
- Raised the Bun minimum version to >=1.3.14 across package metadata, install scripts, and changelog notes.
- Removed the Photon native image pipeline and added SIXEL-based `sixel` support in pi-natives.
- Migrated coding-agent image handling and resizing to `Bun.Image`, including updated tests and a JPEG quality bump to 80.
- Added HTTP/2 fetch bootstrap with HTTPS-only fallback and updated Bun build flags for autoload suppression/`--keep-names`.
- Reduced default image size limits to 1568px and 500KB to match Anthropic's internal thresholds.
- Optimized screenshot compression with 1024px max dimensions, 150KB budget, and 70% JPEG quality for aggressive payload reduction.
- Added fast-path optimization to skip re-encoding when images fit dimensions and are within 25% of byte budget.
- Refactored image encoding strategy to JPEG-only in quality/dimension reduction loops with improved quality ladder steps.
